Compared to the vaccine for children over 12 years old, the amount of active ingredient inoculated at one time is one-third, and children are inoculated twice at intervals of 3 weeks.

We do not recommend group vaccinations at schools, but the policy is to use group vaccinations by local governments or individual vaccinations at pediatric clinics.

“Not an obligation to make efforts”

Due to insufficient data on the efficacy of Omicron strains, vaccination is not currently an "effort obligation" that requires efforts to be vaccinated like those over 12 years old.

Parental consent is required for vaccination, and the Ministry of Health, Labor and Welfare encourages children and parents to fully discuss and consult with their doctors to make decisions based on efficacy and safety data.

Children with underlying respiratory illnesses are at high risk of becoming more severe and are encouraged to receive vaccinations.

● Benefits and Risks

The CDC Vaccine Commission said in November last year that the benefits of vaccination of children were that the vaccine would

be effective in preventing infection and aggravation of the new coronavirus and that

it would

not spread to the surrounding area .

▽ While it has been shown that you can spend your time at school with peace of mind,

risks include

▽ short-term side reactions and

▽ whether or not very rare side reactions such as vaccination-induced myocarditis occur

.

"We have to consider the advantages and disadvantages"

Tetsuo Nakayama, a pediatrician and professor at Kitasato University who is familiar with vaccines, says, "We have to consider the advantages of vaccination by children, the disadvantages of side reactions, and the disadvantages of infection."

As a basis for deciding whether or not a child should be vaccinated, "If a child is infected, even if the child is mildly ill, he / she will continue to receive medical treatment at home. Although it is not, there is a high possibility that it will be possible to get rid of it at least mildly. In addition, vaccination may have advantages such as making it difficult for children to bring it into the home such as parents and grandparents living together. Infections are more likely to occur in situations where people are often in close contact with other people and may need to be vaccinated to some extent. "

On top of that, "Children with underlying illnesses that tend to become more severe need to be proactively promoted. However, there is controversy among experts as to whether it is necessary to inoculate all of them. Children's infections are increasing. However, if there are few people who become seriously ill, there may be an idea that it is not necessary to inoculate, but it is not known in advance who will become severely ill. "

"It is important to understand and decide the vaccine by yourself, not by compulsion, and I want you to acquire the scientific view that you should get the correct information and make your own judgment."
